Abstract

By implanting a synthetic thread (1) shaped as a hairpin a double hair is obtained having a loop (2) which acts as a hair root. The loop and the implanted hair are secured by the subsequent growth of fibrous connective tissue around the loop. This process prevents in particular post-implantation and post-operational infections.

Description

Verfahren zur perkutanen Implantation künstlicher Haare Procedure for the percutaneous implantation of artificial hair
Die vorliegende Erfindung betrifft ein Verfahren zur per¬ kutanen Implantation künstlicher Haare mittels Implanta¬ tions-Nadel.The present invention relates to a method for the percutaneous implantation of artificial hair using an implantation needle.
Bei einem bekannten Verfahren dieser Art, das seit einigen Jahren praktiziert wird, erhält ein, das künstliche Haar bildender Kunststoff-Faden einen Haarwurzelteil in Form eines Auges durch Ueberschlagen des Fadenendes. Wurden früher noch die sich überschneidenden Fadenteile abgebun¬ den oder verknotet, so erfolgt heute eine Schmelzverbindung oder Schmelzhaftung unter Verwendung von Hochfrequenz. Die Meinung besteht dabei, dass ein solches implantiertes Haar relativ leicht wieder entfernt werden kann (etwa auf Grund einer post-implantativen Infektion) , ohne an Veranke¬ rungsqualitäten zu verlieren.In a known method of this type, which has been practiced for several years, a plastic thread forming the artificial hair is given a hair root part in the form of an eye by rolling over the end of the thread. If the overlapping thread parts were previously tied or knotted, today a fusion connection or fusion adhesion takes place using high frequency. The opinion here is that such implanted hair can be removed relatively easily (for example due to a post-implantative infection) without losing any of the anchoring qualities.
Diese Meinung wird aber durch histopathologische Untersu¬ chungen widerlegt. Zum Entfernen des Haars kann zwar der Schweiss- oder Klebepunkt der sich überschneidenden Faden¬ teile gebrochen und dann der Faden in der Regel vollstän¬ dig aus der Haut herausgezogen werden, allerdings unter einer Zugkraft von 110 - 120 gr, was Verletzungen der Haut praktisch unvermeidlich macht. Zudem ist die Hauptursache post-implantativer resp. post-operativer Infektionen, näm¬ lich das scharf antige innere Ende des Fadens, nicht besei¬ tigt; im Gegenteil führt die Schmelzverbindung zu Defor¬ mationen am Faden resp. Haar, was die Möglichkeit der Ver¬ letzung der Haut und somit, die Infektionsgefahr weiter er¬ höht.However, this opinion is refuted by histopathological examinations. To remove the hair, the sweat or glue point of the overlapping thread parts can be broken and then the thread can generally be completely pulled out of the skin, but with a tensile force of 110-120 gr, which practically inevitably damages the skin makes. In addition, the main cause is post-implantation resp. post-operative infections, namely the sharp antigen inner end of the thread, not eliminated; on the contrary, the fusion leads to deformations on the thread or. Hair, which further increases the possibility of skin injury and thus the risk of infection.
Aufgabe der Erfindung ist es nun, das perkutane Implanta- tionsverfahren der vorgenannten Art so zu verbessern, dass Komplikationen, wie post-implantative resp. post-operative Infektionen praktisch nicht mehr vorkommen resp. eine Ent¬ fernung des implantierten Haars ohne weiteres möglich ist.The object of the invention is now to improve the percutaneous implantation method of the aforementioned type so that complications such as post-implantative or. post-operative infections practically no longer occur or removal of the implanted hair is readily possible.
Dies wird erfindungsgemäss dadurch erreicht, dass jeweils durch haarnadelförmiges Legen eines Kunststoff-Fadens ein Doppelhaar gebildet und dabei die Bucht als Haarwurzelteil implantiert wird, um durch nachfolgendes Umwachsen von Bucht und jedem Haarteil des Implantates durch faseriges Verbin¬ dungsgewebe fixiert zu werden.This is achieved according to the invention in that in each case a double hair is formed by laying a plastic thread in the form of a hairpin and the bay is implanted as a hair root part in order to be fixed by fibrous connecting tissue by subsequent regrowth of the bay and each hair part of the implant.
Durch diese erfindungsgemässen Massnahmen ist vergleichswei¬ se dem bekannten Stand der Technik eine komplikationslose Implantation künstlicher Haare zu erwarten, wie Langzeitver¬ suche und klinische Studien nachweisen können. Da die Haupt¬ ursachen post-implantativer resp. post-operativer Infektionen, nämlich Schnittstelle am inneren Fadenende und scharfkantige Deformation am Schweisspunkt der sich überschneidenden Faden¬ teile nach aussen verlegt resp. gänzlich vermieden sind, tre¬ ten Infektionen kaum noch auf. Erscheint ein Entfernen eines Implantates trotzdem angezeigt, lässt sich dieses zudem unter Vermeidung von bisher üblichen Verletzungen einfach heraus¬ ziehen, indem nun zunächst an beiden Haarenden abwechselnd wiegend gezogen und der Faden so von seinen Umwachsungen sanft aber stetig vollständig gelöst und dann ohne nenneswerten Widerstand nach der einen oder anderen Seite herausgezogen wird. Letzteres ist auch dann möglich, wenn das Implantat im Bereich der eingepflanzten Bucht mit einem oder mehreren, Widerlager gegen Zug bildenden Knoten versehen ist.As a result of these measures according to the invention, an uncomplicated implantation of artificial hair can be expected from the known state of the art, as long-term trials and clinical studies can demonstrate. Since the main causes of post-implantative resp. post-operative infections, namely interface at the inner end of the thread and sharp-edged deformation at the welding point of the overlapping parts of the thread relocated to the outside or infections are completely avoided, infections hardly occur. If removal of an implant still appears advisable, it can also be easily removed while avoiding the usual injuries by first pulling alternately on both ends of the hair, so that the thread is gently but continuously completely detached from its changes and then released without any significant resistance one or the other side is pulled out. The latter is also possible if the implant is provided in the area of the planted bay with one or more knots forming abutments against tension.
Ein weiterer sehr erheblicher Vorteil ergibt sich ferner da- durch, dass mit einem Nadel-Hub ein Doppelhaar implantiert wird, was bei vergleichsweise gleicher Implantations-Dichte eine wesentlich höhere Haar-Dichte ergibt.Another very significant advantage is that by implanting a double hair with a needle stroke, which results in a significantly higher hair density with a comparatively same implantation density.
Als Material für das Implantat stehen verschiedenartige Kunst¬ stoff-Fäden zur Verfügung, die aus entsprechenden chemischen und biologischen Tests hervorgegangen sind, wie Polyesterharz¬ einzelfäden von 0,06 bis 0,1mm Durchmesser, die durch Schmelz¬ spinnen eines linearen Polymers aus Polyethylenterephthalat hergestellt werden. Diese Fäden zeichnen sich insbesondere aus durch extrem geringe Toxizität, hohe Wärmebeständigkeit und ein dem natürlichen Haar nahes Feeling.Various types of plastic threads are available as material for the implant, which have emerged from corresponding chemical and biological tests, such as polyester resin single threads of 0.06 to 0.1 mm in diameter, which are produced by melt spinning a linear polymer from polyethylene terephthalate become. These threads are characterized by extremely low toxicity, high heat resistance and a feeling close to natural hair.
Die zu verwendende Implantations-Nadel kann üblicher Bauart sein.The implantation needle to be used can be of a conventional type.
Das erfindungsgemässe Verfahren lässt sich an jeder Stelle des Körpers anwenden, etwa für kosmetische Korrekturen des Haupt¬ oder Barthaares.The method according to the invention can be used at any point on the body, for example for cosmetic corrections of the main or whiskers.
Das erfindungsgemässe Verfahren ist nachfolgend anhand der Zeichnung, die im Ausschnitt ein in die Haut implantiertes künstliches Haar zeigt, näher erläutert.The method according to the invention is explained in more detail below with reference to the drawing, which shows an extract of an artificial hair implanted in the skin.
Durch haarnadelförmiges Legen eines Kunststoff-Fadens 1 wird ein Doppelhaar gebildet, dessen Bucht 2, gegebenfalls ver- sehen mit einem oder mehreren Knoten 2', mittels einer nicht näher gezeigten üblichen Implantations-Nadel unter Durchdringun von Epidermis 3 und Corium 5 in den tiefen Teil des sub- cutanen Gewebes 7 implantiert wird.By laying a plastic thread 1 in the form of a hairpin, a double hair is formed, the bay 2 of which, if necessary, see with one or more nodes 2 ', by means of a conventional implantation needle (not shown in detail) while penetrating the epidermis 3 and corium 5 into the deep part of the subcutaneous tissue 7.
Innerhalb kurzer Zeit werden dann Bucht und anschliessende innere Haarabschnitte des Implantates von faserigem Verbind¬ ungsgewebe 9 vollständig umwachsen und so das Implantat fixiert.Within a short time, the bay and subsequent inner hair sections of the implant are completely surrounded by fibrous connecting tissue 9 and the implant is thus fixed.
Die Darstellung lässt dabei bereits erkennen, dass die Ur¬ sachen der post-implantativen resp. post-operativen Infek¬ tionen, wie vorbeschrieben, vollständig vermieden sind und das Implantat auch nachher ohne Komplikationen entfernt werden kann. The illustration already shows that the causes of post-implantative resp. post-operative infections, as described above, are completely avoided and the implant can also be removed afterwards without complications.
